The fact that Ghost speaks for me every time another character asks me a question gives me the unshakable suspicion that I'm just his undead meat puppet.
Even that first "Will it fly?" in D1 establishes that I can question Ghost, that we are two personalities and that he isn't using dark powers to sublimate my will and force me to do his evil bidding. In D2 that feeling is gone and my guardian has lost all his agency.
I feel like Bungie should give at least a few lines of dialogue to the Guardians...preferably questioning ghost. At least if their intention isn't for Ghost to appear like he's a sinister necromantic agent of evil controlling my light - infused corpse but not granting my the gift of free will or agency
